CARRIAGE-JACK.

SPECIFICATION forming part of Letters Patent No. 245,805, dated August 16, 1881.

Application filed May 31, 1881.

To all whom it may concern.-

Beitknown that 1, CHARLES K. EVANS, a citizen of the United States of America, residingat Madison, in the county of Somerset and State of Maine, have invented certain new and useful Improvements in Carriage-Jacks; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to carriage-jacks, and more especially to that class which is operated by a lever.

The object of the invention is to furnish a carriage-jack of light weight, of simple construction, and one that can he adjusted over the top of carriage-wheel.

The invention consists in the combination of a post, a slotted block adapted to slide thereon, having seats projecting from its lower end, a lever which is pivoted to the upper end of the post, arod or cord connected at one end to the short arm ofthe lever and at the other end to the sliding block, and a notched spring for catching and holding the lever.

Figure 1 is a perspective view of this improved jack. Fig. 2 is a side elevation, show- Fig. 3 is a front view of the sliding block, showing the slot and pin.

Similar letters of refeience indicate corresponding parts in the several figures.

In the drawings, A represents the post which sustains the other parts, of sufficient height to allow the operator to adjust the apparatus to the axle back of the wheel while he stands in front of it in a convenient position to remove the nut or linchpin.

B is the slotted sliding block for supporting the axle. A screw or bolt, 0, provided with a head and washer, is inserted in the post through (No model.)

the slot (1, and holds the block in position. Projecting from the lower end of the block are two seats, (1 d, of different degrees of altitude, which engage the axle and hold it in position. To the upper end of the post is pivoted the lever 0, to the short arm of which is connected a rod or cord, H. The lower end of the rod is attached to the sliding block.

The spring I has its lower end fastened to the post, whileits up per portion passes through a vertical slot in the long arm of the lever, and it stands out at such an angle as will allow it to engage the lever at a convenient distance from the post. Near the upper end of this spring are several notches, 0 0, on the side facing the post, which are designed to catch the lever when it has been pressed down to the desired point, and hold it while the axle of the carriage rests upon the seat of the sliding block. A vertical groove may be formed in the post and a corresponding tongue in the sliding block to prevent lateralswinging of the block; or two screws may be employed, passing through the slot into the post.

Having described my invention, claim as new and desire to secure by Letters Patent--- 1. As an improvement in carriage-jacks, the combination of a post, a slotted block adapted to'slide thereon, having seats projecting from its lower end, a lever which is pivoted to the upper end of the post, arod or cord connecting the lever and sliding block, and a notched spring for catching and holding the lever,suhstantially as described.

2. The combination of the post, the sliding block, the lever provided with a slot through its longer arm, the rod or cord connecting the lever and block, and the notched spring projecting through the slot of the lever, substantially as described.
